Toward a complete functional beauty

I want to go out lightly without a bag! The Hitoe® series was born to fulfill this desire.
Hitoe® Fold Aria" is the ultimate in the Hitoe® series, not only thin, but also small, light, strong, and easy to use.
The sophisticated design and exquisite workmanship have been sublimated into a breathtakingly perfect functional beauty.

Aria" is as light as air.


Aria" means "air" in Italian. It also means a lyrical solo song in opera and religious music.
Like air, you forget it even exists. Yet it is beautiful and full of originality.

Hitoe® structure" stands out for its thinness


Wallets become thicker when cards and coins overlap. The Hitoe® structure solves this problem. Cards and coins are not stacked on top of each other, making the wallet overwhelmingly thinner.
An astonishingly thin 9mm (at the thickest part), even when 5 cards are stored.
Size: Only 89mm x 91mm
Weight: approx. 33g
Holds up to 15 banknotes, 20 coins, and 6 cards.
Even when fully loaded, it is overwhelmingly thin.

Well-honed design

1 "Perfection is a state in which no further sharpening is possible.

These are the words of Saint-Exupéry, the author of "The Prince of Wales.
Hitoe® Fold Aria's simplicity of design and comfort are the height of perfection: smooth opening and closing without hardware, easy entry and exit, and a thinness that makes you forget it's even in your pocket.

ミニマルなデザイン - HITOE FOLD ARIA

2 Wallets this thin

The edges are not "rolled in" but have a "seam allowance". This is in pursuit of "thinness. If it is rolled in, the size will be smaller, but the overlap of leather will increase and it will become thicker.
This detail is faithful to the ideal we are aiming for.

端部比較 - HITOE FOLD ARIA Size comparison by edge treatment method

Even in pursuit of thinness, the leather is thick enough, and the texture of tension and firmness are also important.

3 Beautiful details

Precise and delicate stitching, transparently polished koba (cross-section of leather) that reveals the overlapping layers of leather, and thin lines (nenpiki) drawn around the edges with a heated iron. Even the koba of suede, which is said to be impossible to polish, is polished with great care, pursuing beauty down to the smallest detail.

端部処理 - HITOE FOLD ARIA Beautiful edge treatment of the seam allowance

4. Top quality manufacturing method

All parts are made of thin leather with a "sticky" (glued all over ) finish. This technique is said to be the highest luxury of leather products. Two pieces of thinly stripped leather are pasted together to create a stronger, lighter, and thinner finish. It takes a great deal of experience and skill to create a leather that looks like a single piece of leather, even when folded and bent.

刻印 - HITOE FOLD ARIA Pursuing simplicity, the engraving is hidden under the card.

5 Long and beautiful use

Most problems with wallets are caused by hardware and sewing. No hardware is used at all, and only four stitches are used.
In addition, the corners, which are prone to pain, are made more durable by layering the outer and inner leather. The seam allowance is as small as possible, and the design prevents the bag from losing its shape even when used in the back pocket of trousers.
It is a simple and sturdy construction that can be used beautifully for a long time.

角の補強 - HITOE FOLD ARIA The corners are layered with leather for durability.

6 Design in accordance with the providence of nature

Why is the Golden Ratio so beautiful?
The golden ratio 1:1.618 is the ratio of the length and width of a rectangle consisting of a spiral of squares with the Fibonacci sequence ( 1,2,3,5,8,13,21...) as one side. (The
Fibonacci sequence is hidden everywhere in nature.
Tree branches, the number of petals, sunflower seeds, seashells, typhoons. It is also found in art of the highest beauty, such as the Pyramids, the Parthenon, and the 36 Views of Mount Fuji.
Deeply related to nature and the order of life, hence the golden ratio based on the Fibonacci sequence, which also tugs at the heartstrings.
It is not important to achieve the golden ratio. It is the proportions from the smallest detail to the whole that make the Fibonacci sequence work to create a well-rounded design that resonates with the heart.

フィボナチ数列 - HITOE FOLD ARIA Design based on the Fibonacci Sequence

Easy to use and beyond

Not only is it thin, it is also comfortable. We pursue not only ease of use but also comfort.

1 New concept of using the card to be stored as a clasp

We have devised an "inner hook (patent pending) " that hangs not outside the wallet but on the card to be stored and uses the card itself as part of the clasp. It is a smart leather hook that fits inside the wallet and is not shown on the front.

カードに掛ける留め具 - HITOE FOLD ARIA Inner hook that hangs on a card integrated with the bill holder

It not only serves as a clasp for the wallet, but also prevents cards from falling out and allows for speedy opening and closing.

カードの落下防止 - HITOE FOLD ARIA Stays inside and prevents cards from falling out unexpectedly

2. Clip it with leather, and that's it.

The inner hook allows for a flat appearance that can only be clipped with leather. No hardware, flap, or other extraneous items protrude, so there is no snagging in the pocket.

正面 - HITOE FOLD ARIA Minimalist shape with no waste

3. Smooth opening and closing with the "U" shape

By bending the boundary between the card and coin pockets in a "wedge" shape, the inner hook on the card can be easily removed. With this one action, coins, bills, and cards can all be accessed for quick checkout.

開き方 - HITOE FOLD ARIA Smoothly opens and closes by bending it in a "crisscross" shape.
The trick is to bend it in a "crisscross" shape and not touch the inner hook.

4. Leave the banknote in place

Just insert bills without folding them. Highly visible and easy to take out. The bill holder is designed to be continuous with the inner hook. The curve of the bill holder serves as a guide, allowing smooth insertion and removal without snagging.

Smoothly insert and remove cards without touching the bill holder.

5 Cards are safe and smooth

No need to worry about cards falling out.
Once the wallet is closed, cards will not fall out. The wallet is designed to prevent cards from slipping out while in use. (*Intellectual property rights to be acquired) The
feeling of sliding cards in and out is comfortable and smooth.

Extra cards are held in the bill holder to prevent stretching of the leather in the card pocket. It does not interfere with the opening and closing of the wallet.

開き方 - HITOE FOLD ARIA Extra cards can be placed in thewallet holder.

6 Shallow coin pocket

A shallow coin pocket allows you to quickly find and remove the coins you need.
No need to worry about coins spilling out when the wallet is closed. The short flap prevents overflow while the wallet is in use.
999 yen (15 coins ) can be stored in the pocket.

Q. What is the difference between Hitoe Fold, Hitoe Fold Aria, and Hitoe Fold Less?

Hitoe Fold Aria" and "Hitoe Fold Less" are our flagship models, which are uncompromising in material, design, functionality, and detailing. The Hitoe Fold Aria can hold 6 cards, while the Hitoe Fold Less can hold 3 cards.
Hitoe Fold" is the second grade of this concept, realized in leather that you can enjoy the texture and the change of material over time. It can hold up to 7 cards.
Other differences are as follows

1 Material
Hitoe Fold" utilizes high quality thick leather (Italian vacchetta leather), which has the characteristics of leather as it is and allows the user to enjoy its leatheriness. The floor (back side) of the leather has been treated to minimize shedding in order to improve the sliding of banknotes and other items.
The "Hitoe Fold Aria" and "Hitoe Fold Less" have luxurious specifications with leather laminated on all parts, and the silver surface is double-layered to achieve both thinness and durability.

2 sizes
Flat size
, Hitoe Fold w92 x h92 mm
, Hitoe Fold Aria w89 x h91 mm
, Hitoe Fold Less w89 x h89 mm

Thickness (thickest part around the clasp)
- Hitoe Fold approx. 10mm (when 5 emboss-less cards are stored ) - Hitoe Fold

Aria approx. 9mm (when 5 emboss-less cards are stored)
- Hitoe Fold Less
There is a slight individual difference.
Please add 0.2-0.3mm per card for embossed cards.

Due to the difference in the feel of the materials, you will probably feel the difference more than the numbers when you hold it in your hand.

手のひらサイズ Left: Hitoe Fold ( 5 cards) Middle: Hitoe Fold Aria (5 cards) Right: Hitoe Fold Less (3 cards)

3 Difference in feel
Depending on the stitching on the side of the bill holder, the "Hitoe Fold" may feel a tugging sensation when inserting or removing banknotes from the side. Also, the sliding of banknotes may cause a little more friction.

The "Hitoe Fold Aria" and " Hitoe Fold Less" have a card pocket that is designed to prevent cards from falling out even when the clasp is removed.

Q. Do you have any tips for opening and closing?

If you bend the border between the coin and the card in the shape of a "ku", the hook on the card will be released and the card can be used smoothly.

How to bend the opening and closing (e.g. Hitoe Fold Aria)

When closing, lightly press down on the top of the flap and bend the flap in a "ku" shape so that the hook fits naturally into the card. The trick is to keep your fingers away from the hook.

To close, simply slide the flap while holding it down (e.g. Hitoe Fold).

Q. When I close it, it distorts.

This is due to misuse of the hook on the outside of the wallet. Please hang the hook only on the card to be stored.

(Example: Hitoe Fold)

Q. Will coins or cards overflow?

If you hang the hooks on the cards to be stored and close the wallet, there will never be an overflow of coins or cards. When the wallet is opened, the lid of the coin pocket holds the coins in place and prevents them from overflowing. However, if the wallet is used horizontally, coins may overflow. Please use the card vertically.
